Quartz Scepter showing epitaxy
stock #18.1-655
Boron Pit, Dal'negorsk, Kavalerovo
Primorsky Kray, Far Eastern Region, Russia
4.8 x 2.2 x 2 CM (miniature)
price: $160
Spring 2019

A new find from the great Dalnegorsk (this from the Bor pit). Choice sceptered quartz in excellent condition, with no chips or dings that hosts smaller Quartz crystals in epitaxial arrangement. The shaft of the scepter is composed of hundreds of tiny oriented small Quartz crystals stacked in perfect epitaxial alignment. These crystals and the "accessory" crystals are of the Cumberland or "Beta" type with little or no prism faces just two terminations joined. The smaller accessory quartz are also epitaxially oriented and have some inclusions and adhering matter that gives them a yellowish color. Some have called these Citrine but I think this color is simply a result of these inclusions. A few tiny crystals of Hedenbergite are on the base of the shaft as well. A choice, undamaged example and a nice scepter with amazing structure when examined closely.
Olmeite
stock #19.1-237
N'chwaning Mine, Kalahari Fields, Kuruman
Northern Cape Province, South Africa
3.8 x 3.4 x 2.2 CM (small miniature/ large thumbnail (toenail))
price: $90
Spring 2019

A cute specimen of Olmiite crystals in spherical form on contrasting matrix. Nice luster and fair pink color, these were once all labeled as Poldervartites (a rare mineral at the time of the find) later re-studied and classified as Olmiite (also at that time a rare mineral). This discovery was sizable and enough good specimens found to allow collectors to own a nice piece without major financial pain. In good condition and a good value.
Apatite (fluorapatite)
stock #18.1-703
Okatjimukulu Farm 56, Karibib Region
Erongo Region, Namibia
3.1 x 3 x 1.7 CM (small miniature/ large thumbnail (toenail))
price: $360
Spring 2019

Flattened hexagonal crystal of deep purple zoned Apatite without matrix. From the finds several years back in the Karibib area of Namibia, this has an etched, frosted luster and good translucency. The crystal is not complete on all edges (typical for this find) but it is undamaged and shows complex recrystallization on some edges. The color is super intense in person, a very nice sizable purple Apatite.
Babingtonite on Prehnite
stock #8.1-233
Meigu County, Liangshan Prefecture
Sichuan, China
5.1 x 4.2 x 3.1 CM (small cabinet/large miniature)
price: $600
Spring 2019

Well perched sharp and lustrous Babingtonite crystals on contrasting green Prehnite. The finds of these incredible Babingtonites in Meigu redefined this specie and are considered by far the worlds best. The clear form and bright black luster gives this specimen a strong presence. Esthetic and in fine condition there are a few clear Quartz crystals scattered about adding a nice sparkle as well. Damage free and esthetic.
Nickelskutterudite (formerly Cloanthite) - Exceptional classic
stock #0438-JM-568
Schneeberg Distict, Erzgebirge
Saxony, Germany
7.8 x 5.7 x 2.9 CM (cabinet)
price: $1750
Spring 2019

A superb, unusually well formed classic German specimen from the famed Schneeberg mines. The quality is top notch, see the outstanding recent Mineralogical record article on this locale. Sharp, well isolated individual crystals (reaching over 2 CM) contrast with small patches of Cumberland habit druzy Quartz and what seems to be Wendwilsonite. This is ex John Marshall collection piece acquired by him over 50 years ago. The crystal forms on this are well pronounced and show clearly the cubo-octahedral forms with curved faces. These are far more distinct and three dimensional than typical. The display face is in fine, undamaged condition, which is remarkable for this brittle mineral. The only damage to note is on part of the outer edge. Very rare to find any decent specimens available but this one is far beyond that, as fine as any major piece, yet not insanely expensive for a classic..
Microlite on Clevelandite -USA classic
stock #13.1-406
Rutherford Mine, Amelia County
Virginia, United States
5 x 4.6 x 3.2 CM (miniature)
price: $140
Spring 2019

A single glassy Microlite octahedron is tucked in a small cleft between large Cleavelandite blades. From the Rutherford mine in Amelia County, Virginia. The Microlite has gemmy areas and is 5MM across.
Calcite- Violet color gem clear
stock #16.1-316
Mina San Martin, San Martin, Municipio de Sombrerete
Zacatecas, Mexico
4.9 x 4.8 x 3.5 CM (miniature)
price: $290
Spring 2019

Glasslike faces with high luster and very sharp edges define this older Mexican Calcite. The crystal is twinned and transparent with fine violet color throughout. The reflective faces makes this hard to show to well in photographs but in person it is striking. The display side of the piece is in fine shape, the bottom and rear are contacted or broken in areas that can be concealed by display angle. otherwise only very tiny edge rubs are found with 10X loupe, this is naked-eye clean and impressive for any Calcite.
Apophyllite on Stilbite finger -well pocket find
stock #18AX-21-024
Rahuri, Ahmadnagar District,
Maharashtra, India
7.4 x 4 x 1.6 CM (cabinet)
price: $400
Spring 2019

A fine example of the radiating habit of flat tip green Apophyllite crystals in flowerlike form. The stalk of Stilbite is a choice contrasting matrix for the gem clear Apophyllites. in perfect, undamaged condition the Apophyllites are water clear at the tips and nearly colorless, they grade to a fine mint green lower down and the color is transmitted through the entire crystal. very good value from the second well pocket (there have been at least 4 in 12 years, each a little different). This was a unique small pocket with the fingerlike stalks of Stilbite in stalactitic form.
